Throwing clay at a toy train car. 1) A very strong boy throws a wad of clay with mass m. = 0.2 kg at a speed of v. = 30 m/s at a stationary toy train car sitting on a horizontal section of a toy train track, as shown in the diagram (which is not drawn to scale). The clay sticks to the back of the train car and remains stuck to the train following the collision. The train car has mass m,= 0.4 kg. You may neglect friction of the wheels and track. a) What is the speed of the train car immediately after it is struck by the clay? b) What fraction of the clay's initial kinetic energy was lost to forms of energy other than kinetic energy as a result of the collision? c) The moving train car then ascends a 30° incline that rises a total of Ah = 15/4 m (3.75 m) above the lower section of the track. What is the speed of the train car once it reaches the top of this incline?

please type out or diagrams so that it is easy to read

where did you get the equation you used from?

Hello, I really need help with Part A, PART B, AND PART C BECAUSE I don't understand it is there any chance you can help me with the problems and can you label them as well
